There are several potential causes of crooked or misshapen fingernails. Some of the most common causes include trauma, underlying medical conditions, and genetics.
Trauma to the fingernail, such as a direct blow or a crush injury, can cause the nail to grow crooked or misshapen. The nail matrix, which is the area of cells at the base of the nail responsible for nail growth, can be damaged by trauma, leading to a deformity in the nail.
Underlying medical conditions can also cause crooked or misshapen nails. For example, conditions such as psoriasis, eczema, and lichen planus can affect the nail matrix and cause the nails to grow abnormally. Fungal infections, such as onychomycosis, can also lead to nail deformities.
Genetics can also play a role in the shape of the nails. Some people may be more prone to developing crooked or misshapen nails due to their genetic makeup.
In most cases, crooked or misshapen nails are not a cause for concern and do not require medical treatment. However, if the deformity is accompanied by other symptoms or if the nail becomes painful or infected, it is important to consult with a healthcare provider for evaluation and treatment.
In conclusion, crooked or misshapen nails can be caused by trauma, underlying medical conditions, or genetics. While they are often not a cause for concern, it is important to seek medical evaluation if the deformity is accompanied by other symptoms or if the nail becomes painful or infected.
